Adopted and named by abolitionists as a symbol of freedom, the Liberty Bell has served as an icon of justice for oppressed groups everywhere. In 1915 women suffragists in Pennsylvania forged a replica of the bell, known as the Justice Bell, which toured Pennsylvania with its clapper chained to its side. The clapper would not ring until justice was achieved and women won the vote. Courtesy of The Historical Society of Pennsylvania Collection, Atwater Kent Museum of Philadelphia.
